A prep school student who is struggling to get into Keio University after repeated failures. When he goes once again to take the entry exams, it is love at first sight (for him, at least) when he meets Mieko Yotsuba. When she is accepted but he is not, he decides to lie to her and says that he was accepted. He lives with his cousin, Urara Kasuga, who has feelings for him and affectionately calls him "Tonma-chan" though he is too dense and love-struck for Mieko to notice.
